Looks like Romano to me and what part is the 23" arms on?
The "23 inch arms" is when Flex is training arms, and he says "______ here is are waterboy..." Dude is wearing a white long sleve shirt, and Flex is then saying after asking about showing his arm...he or Rico in the background goes "Stretch your shirt..."
Dude says he'll be back, and Flex says, "Watch he'll never come back, 'uuh, i gotta go eat'...bastard."
